Move 6x to the right side
2y = -6x - 14
Divide all numbers by 2 to isolate the variable
2y/2 = -6x/2 - 14/2
y = -3x - 7
You would need to buy 3 because you need 227.2 grams of raisins and that’s 3 bags
Using the formula a^2-b^2=(a-b)(a+b)
you get
(1/2x^2-2) (1/2x^2+2)
R = radius of the cylinder
V = (1/3)Pi c^2 h for a cone.
and c = r/2 and h = u
so Volumn of the cone is (1/3)Pi(1/4)(r^2)r = (1/12)Pi r^3
